| Zusammenfassung: | The invention discloses a method for processing high-concentration organic waste water. In the invention, a three-stage treatment process of anaerobic treatment, aerobic treatment and two-stage precipitation is adopted, the high-concentration organic waste water passes through a circulating water distribution mixer, an internal-external dual-circulation high-efficiency anaerobic reactor, a first-stage settling pond and a flocculation precipitation tank in turn for treatment according to differential hydraulic residence time, so that the concentration of chemical oxygen demand (COD) resided in the effluent of the high-concentration organic waste water can be greatly reduced, and the total COD removal rate of the three stages is over 99 percent. The method improves the efficiency, stability and reliability of waste water biological treatment, guarantees that the waste water can reach standards and be recycled, and can realize the recycling of the waste water. |
